Answer:

You will have $623.3441462 in your account after 7 years

Step-by-step explanation:

The formula of the compounded interest is A = P [tex](1+\frac{r}{n})^{nt}[/tex] , where

∵ You are opening a savings account with $500  

∴ P = 500

∵ The bank offers 3.2% interest, compounded yearly

∴ r = 3.2% ⇒ divide it by 100 to change it to decimal

∴ r = 3.2 ÷ 100 = 0.032

∵ The interest is compounded yearly

∴ n = 1

∵ The time is 7 years

∴ t = 7

→ Substitute these values in the rule above to find A

∵ A = 500 [tex](1+\frac{0.032}{1})^{1(7)}[/tex]

∴ A = 500 [tex](1.032)^{7}[/tex]

∴ A = 623.3441462

∴ You will have $623.3441462 in your account after 7 years

Complete Question

If $12000 is invested in an account in which the interest earned is continuously compounded at a rate of 2.5% for 3 years

Answer:

$ 12,934.61

Step-by-step explanation:

The formula for Compound Interest Compounded continuously is given as:

A = Pe^rt

A = Amount after t years

r = Interest rate = 2.5%

t = Time after t years = 3

P = Principal = Initial amount invested = $12,000

First, convert R percent to r a decimal

r = R/100

r = 2.5%/100

r = 0.025 per year,

Then, solve our equation for A

A = Pe^rt

A = 12,000 × e^(0.025 × 3)

A = $ 12,934.61

The total amount from compound interest on an original principal of $12,000.00 at a rate of 2.5% per year compounded continuously over 3 years is $ 12,934.61.

Answer:

The angle m ∠ W = 33°

The length of XZ = 9.8 units

The length of WX = 15.1 units

Step-by-step explanation:

Given

The right-angled triangle ΔWXZ

We know that the sum of the measure of angles in any triangle is 180°.

Therefore,

m ∠ W + m ∠ X + m ∠ Z = 180°

substiute m ∠ X = 90° and m ∠ Z = 57° in the formula

m ∠ W + 90° + 57° = 180°

m ∠ W + 147 = 180°

m ∠ W = 180° - 147

m ∠ W = 33°

Therefore, the angle m ∠ W = 33°

NOW,

Determining the lengths of WX and XZ

Length XZ

Using the trigonometric ratio

The adjacent to 57° is XZ.

so

cos 57° = adjacent / hypotenuse

substituting adjacent = XZ, and hypotenuse = 18

cos 57° = XZ / 18

XZ  = 18 × cos 57°

XZ = 9.80 units

Therefore, the length of XZ = 9.8 units

Length WX

As

m ∠ W = 33°

The adjacent to m ∠ W = 33° is WX.

so

cos 33° = adjacent / hypotenuse

substituting adjacent = WX, and hypotenuse = 18

cos 33° = WX/ 18

WX = 18 × cos 33°

WX = 15.1 units

Therefore, the length of WX = 15.1 units

Summary:

The angle m ∠ W = 33°

The length of XZ = 9.8 units

The length of WX = 15.1 units

Answer: x=8 and y=4

Step-by-step explanation:

14x+22y=200                                x=8

14(12-y)+22y=200

168-14y+22y=200

-168                 -168

-14y+22y=32

8y=32

8y/8=32/8

Answer:

13.5

Step-by-step explanation:

equilateral triangle (all sides are equal) thus, if one side is 4.5 u will need to take 4.5x3=13.5

Well let me help.

For the first Question, the question is asking for the perimeter of the plot so assuming the plot is a rectangle, the perimeter will be (2*3)+(2*4.3)

=6+8.6

=14.6km.

Question 2

The problem involves finding the perimeter of the triangular garden. since the garden is an equilateral triangle, the perimeter will be thrice the side given ("equilateral" means "equal sided triangle"). So the answer will be 3*4.5

= 13.5 km.

Question 3

Same type of question as Q2 but this type is isosceles triangle (only two equal sides with one being different)

So the perimeter will be (2*15)+20

=30+20

=50km.

I hope this'll help

[tex]4x + 7y = 41 \\ 4 \times ( - 7) + 7 \times ( - 16) = 41[/tex]

Answer :

(1) The radius of a circle is 1.5 m.

(2) The diameter of a circle is 28 ft.

(3) The radius of a circle is 10 in.

(4) The circumference of circle is 47.14 m.

(5) The circumference of circle is 44 yd.

Step-by-step explanation :

Part 1:

Given: d = 3 m

Now we have to determine the radius of circle.

As we know that:

Radius of a circle = [tex]\frac{Diameter}{2}[/tex]

So,

Radius of a circle = [tex]\frac{3m}{2}=1.5m[/tex]

The radius of a circle is 1.5 m.

Part 2:

Given: r = 14 ft

Now we have to determine the diameter of circle.

As we know that:

Radius of a circle = [tex]\frac{Diameter}{2}[/tex]

So,

Diameter of a circle = [tex]Radius\times 2[/tex]

Diameter of a circle = [tex]14ft\times 2=28ft[/tex]

The diameter of a circle is 28 ft.

Part 3:

Given: d = 20 in

Now we have to determine the radius of circle.

As we know that:

Radius of a circle = [tex]\frac{Diameter}{2}[/tex]

So,

Radius of a circle = [tex]\frac{20in}{2}=10in[/tex]

The radius of a circle is 10 in.

Part 4:

Given: d = 15 m

Now we have to determine the circumference of circle.

Formula used:

[tex]C=\pi d[/tex]

where,

C = circumference

d = diameter

So,

[tex]C=\frac{22}{7}\times 15m[/tex]

[tex]C=47.14m[/tex]

The circumference of circle is 47.14 m.

Part 5:

Given: r = 7 yd

Now we have to determine the circumference of circle.

Formula used:

[tex]C=\pi d[/tex]

or we can write,

[tex]C=\pi (2\times r)[/tex]

where,

C = circumference

d = diameter

r = radius

So,

[tex]C=\frac{22}{7}\times (2\times 7yd)[/tex]

[tex]C=44yd[/tex]

The circumference of circle is 44 yd.

The percentage of students in Mrs. Murphy's class who have blonde hair will be 20%.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

There are 25 students in Mrs. Murphy's math class. Of these students, 10 have brown hair, 8 have black hair, 5 have blonde hair, and 2 have red hair.

Then the percentage of students in Mrs. Murphy's class who have blonde hair will be

Total students = 25

Then we have

[tex]\rm P = \dfrac{5}{25} \times 100\\\\P = 0.20 \times 100\\\\P = 20 \%[/tex]

Answer:

We get tₙ: [tex]\mathbf{t_n=an}[/tex]

10th term is [tex]t_{10}=10a[/tex]

Step-by-step explanation:

The given arithmetic sequence is: a,2a,3a

We need to find tₙ and tenth term

Finding tₙ

The formula used is: [tex]t_n=t1+(n-1)d[/tex]

We need to find d, the common difference

a₁ = a

a₂ = 2a

We can find common difference using the formula:

[tex]t_n=t_1+(n-1)d\\Put\:n=2\\t_2=t_1+(2-1)d\\2a=a+d\\d=2a-a\\d=a[/tex]

So, we get common difference d = a

Now, finding tₙ

[tex]t_n=t_1+(n-1)d\\t_n=a+(n-1)a\\t_n=a+an-a\\t_n=an[/tex]

So, we get tₙ: [tex]\mathbf{t_n=an}[/tex]

Now, finding 10th term

By putting n=10 in the equation [tex]t_n=an[/tex]

[tex]t_n=an\\Put\:n=10\\t_{10}=a(10)\\t_{10}=10a[/tex]

So, 10th term is 10a
